PixelBrick : I am interested in buying Contra for the NES if it is at a sufficient price. What are you looking to get for it?

TreasurePlanet23 : You want to buy it? I wasn't planning on selling these to people on Vizzed though. Name a price, and I can figure out a way to sell it for you. It has to be U.S.D though.

You are never too old for video games . Honestly, I don't think you should sell any of them. You will probably regret it in the future. You will want to play them for nostalgia or collection reasons. And you say now that you don't want kids, but that will probably change in the future. I would keep them if I were you.

You have a nice collection. If it were me I wouldn't sell any but, that's just because I like to go back and play games for nostalgia. Although, you can play most on here if you wanted. That being said, I'd be interested in the N64 and a couple of the games namely the Zeldas, Smash Bros and maybe a couple of others. I do have a birthday coming up and maybe I can talk someone into buying me them for that or if you want to set something up that'd be cool too.

I had an N64  and those games back in the day but it was my brothers and he ended up selling them. I was pretty upset about that.

Oh yeah, you should sell them all if you aren't going to be playing them or passing them along. You could probably get some good money selling on eBay or something. 

PixelBrick : I would honestly sell Toy Story because its my least favorite of the games that you currently have but then again that's just me. I really don't like the Toy Story game.

PixelBrick : "Growing out of video games"

Is it possible if buy a console and game? If so I would like to buy your N64 and Majora's Mask (do you have the expansion pack required). Just give me a price for the both and I will see if that within my budget. 

Oh my gosh you are getting rid of this massive collection. Are you sure you want to do this!!

MechaMento : I have multiple Nintendo 64 consoles. I'll give prices for them. I may not be able to ship it to you soon though. I am very busy this year.

Charcoal N64: $30

Gold N64: $95

Jungle Green N64: $96

Fire Orange N64: $105

Controller: $10

Majora's Mask (boxed): $45

Majora's Mask: $20

PixelBrick : I would say keep them all, if you ever have kids and they become gamers, you will have a wide selection of games for them to try!

PixelBrick : They are all in good condition right? I will go for the Charcoal N64, I think the color is fine. I am not fussed too much on how rare it is. Now I will ask the same question again and say. Do you have the pack required to actually play the game, also will it be free if I buy the game or will I have to charge extra.

PixelBrick : sell these games:
Friday the 13th
A Bug's Life
if you have an expansion pak and the expansion pak tool, i would buy it for 16,000 Viz.
and how do you have banjo threeie??????? wtf man!

"Banjo Threeie"!? What the heck? Pics.

I still enjoy playing my old games and I do like to collect them. I rarely sell any of my games. I would only sell one if I really didn't care for it.

MehaMento:Yes, it will be no additional charges. I keep all my video game equipment clean, so yes in good condition. And if you buy a console from me, you get a free Game Boy with it too. 

Opti101 : It's the third Banjo Kazooie game

noah101:I don't remember Banjo Threeie being rare.

PixelBrick : The boxed SMB3, Power Gloves, and Boxed N64 games will all fetch a hefty price. I suggest going listing them on ebay or amazon. Banjo Threeie doesn't exist, not quite sure what you mean by that. You have a nice collection that will definitely fetch a great price.

SheLikesCloth : >Boxed Super Mario Bros 3 and Power Glove. Are you gonna reenact that scene from the movie Beethoven where both the boy and girl are playing Mario 3 and they're mashing the buttons on their controllers at the same time and the boy is playing with the power glove?  

PixelBrick : While I won't deny that's a great idea, I wasn't the one planning on buying them
I'm 15 and only get about $5 a month. I'm saving for an HDTV and a WiiU currently.

You aren't too old to play old classic video games, I‘m not, I would understand if it was due to financial issues, but other than that, even if you don’t have kids, at least you have something to look at in the future.
